derivatives from ninhydrin, 1,2‐phenylenediamine, sarcosine, 1,3‐indanedione, and aldehydes via cascade reactions under mild conditions, in which 1,3‐dipole azomethine ylide and the dipolarophile were simultaneously generated in situ. This novel method is complementary to the classical Huisgen cycloaddition in that it is well‐suited to the preparation of dispiroindenoquinoxaline pyrrolidine derivatives.
已开发出一种有效且直接的五组分级联方案,可在温和条件下通过级联反应从茚三酮,1,2-苯二胺,肌氨酸,1,3-茚满二酮和醛中合成高度取代的二螺并茚并喹喔啉吡咯烷衍生物,其中1, 3偶极偶氮甲亚胺叶立德和双极亲叶菌是在原位同时生成的。该新方法非常适合经典的Huisgen环加成反应,因为它非常适合于制备双螺并茚并喹喔啉吡咯烷衍生物。
